| Outline of Final Research Achievements |
In this study, I have developed a finite element method (FEM) based on the model order reduction (MOR) to realize fast three-dimensional optimization. I have shown that transient quasi-static electromagnetic fields can be fast analyzed using the proper orthogonal decomposition (POD) which is one of the MOR methods. I have shown that POD-based FE analysis is useful and effective for shape optimization of antennas. Moreover, I have proposed the sub-domain MOR in which the domain is automatically subdivided into strongly saturated and other regions to latte of which MOR is applied, and block MOR in which the angle-domain for rotating machine analysis is subdivided into small ones in each of which the basis vectors for MOR are constructed. I have also shown that using the MOR technique, the equivalent circuits can directly be synthesized from FE models of electric apparatus.
